Kimberley, 31, said: "I just want to be honest and hopefully people will find that interesting.

"I'm quite a private person so I think it will be a surprise for me to be so honest."

She appears in upcoming children's comedy All Stars and stepped out on the red carpet at the film's premiere tonight with co-stars Ashley Jensen and Ashley Walters.

Ugly Betty actress Jensen added she would be staying in the UK now.

She said: "I was in the US for six years but I always knew it wasn't forever. Working over here you can do more variety because projects are three months rather than a year."

Jensen plays the part of youth worker Gina in a youth centre under threat of closure. The children in the cast, including Horrid Henry's Theo Stevenson and Got To Dance winner Akai Osei-Mansfield, set about organising a dance show to raise money for the centre.

Former Shrek The Musical star Walsh plays the main character's mother.

Other famous faces appearing in the cast include singer Javine Hylton, comedian Kevin Bishop and star of Green Wing and Friday Night Dinner Mark Heap. All Stars is released in cinemas on May 3.
